Patents by Inventor Ove OLL

Ove OLL has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Method of forming a dielectric through electrodeposition on an electrode for a capacitor
    Patent number: 10087541
    Abstract: The present invention relates to a method for forming a capacitor having carbon or metal electrodes and an electrolyte which is also a source of electropolymerisable anions. Applying a sufficiently positive voltage, a thin dielectric layer forms at the positive electrode, enabling the use of cell voltages higher than 3.5 V. The construction and characteristics of capacitors with 5, 6.3, and 10 V of cell voltages, having reduced graphene oxide electrodes and an ionic liquid electrolyte, are shown.
